Sanwa has recently announced the availability of a slim mini portable projector that works in combination with your iPhone 4 or 4S.
The new Sanwa 400-PRJ011 is powered by its own 2,100mAh battery which happily can also charge your own iPhone battery.
The projector has an autonomy of five hours and can provide 2.5 hours of steady projection.
As you can see from the video, it is capable of projecting still or video images on any flat surface up to a size of 65-inches at 640 × 360 resolution.
Available for now only in Japan.
